### PostHog Integration for React Router v7 - Follow the four-step setup workflow to integrate PostHog analytics into Data mode applications. - Use environment variables for keys and mirror the implementation patterns found in the provided example project. - Trigger analytics in event handlers, avoid useEffect for state logic, and use specific headers to maintain user identification.

### PostHog Ruby on Rails Integration - Install the posthog-rails gem and use PostHog.init in an initializer to manage the client lifecycle automatically. - Securely store API keys using environment variables or Rails credentials instead of hardcoding them in your application. - Use class-level PostHog.capture and PostHog.identify methods to track events and associate users across backend and background jobs.

### PostHog Feature Flags for Ruby - Install the posthog-ruby gem and initialize the client using environment variables for API keys to ensure secure configuration. - Implement server-side flag evaluation to prevent UI flickering and use boolean flags as the default for simple feature toggling. - Always call client.shutdown in an ensure block for scripts and CLIs to prevent data loss and ensure proper event flushing.

### PostHog Node.js Error Tracking - Initialize the SDK with enableExceptionAutocapture set to true and use environment variables for all sensitive configuration keys. - Implement captureException in global error handlers and specific catch blocks to ensure comprehensive visibility into application failures. - Upload source maps to resolve stack traces and configure flush settings to match the lifecycle of your server or serverless process.

### PostHog Log Ingestion for Other Languages - Configure OTLP exporters to send logs directly to PostHog's ingestion endpoint using the OpenTelemetry protocol. - Use environment variables for all sensitive configuration, including PostHog project keys and OTLP endpoints. - Implement structured logging with key-value pairs to enhance searchability without replacing existing application logging logic.

### PostHog Integration for TanStack Router - Initialize PostHogProvider in the root route to ensure global access to the analytics client across all child routes. - Track pageviews using TanStack Router navigation events and capture user actions directly within event handlers, avoiding useEffect. - Identify users during authentication and maintain session correlation by passing distinct IDs via headers in API requests.

### PostHog Integration for Nuxt 3.6 - Follow the four-step setup workflow to initialize PostHog analytics within your Nuxt 3.0 to 3.6 application. - Use environment variables for all PostHog keys and maintain consistency by following the provided example project patterns. - Identify users during authentication events and use specific headers to correlate client-side sessions with backend requests.

### PostHog Integration for React Router v7 - Implement PostHog analytics using the declarative pattern by following the four-step setup workflow and referencing the example project. - Use environment variables for API keys and trigger analytics capture directly within event handlers rather than inside useEffect hooks. - Identify users during authentication and maintain session correlation by passing distinct IDs via headers for backend-integrated flows.

### PostHog Integration for Nuxt 4 - Follow the four-step setup workflow to integrate PostHog analytics into your Nuxt 4 application. - Use environment variables for all PostHog keys and follow the provided example project patterns for implementation. - Identify users during authentication and use specific headers to maintain session correlation between frontend and backend.

### PostHog Astro View Transitions Integration - Use the is:inline directive and a reusable PostHog component to initialize analytics within Astro layouts. - Configure capture_pageview to history_change and use the astro:page-load event to ensure tracking persists during soft navigation. - Securely manage project tokens via PUBLIC_ environment variables and maintain user correlation using custom request headers.
